Hi All,

Running into an issue with a task exiting due to a bad exit code and stays stuck in running (using Orion).
```21:24:17.733 | ERROR   | prefect.flow_runner.subprocess - Subprocess for flow run '3919d4eb-17ed-4847-bca9-577d8d31d702' exited with bad code: -6```
I see this emitted in the agents log, but the task stays stuck in running.

Thoughts?

thanks for opening an issue - let's keep the discussion there, we've seen something similar already, Michael will certainly be able to explain it more but the main issue is that Matplotlib GUI can only run in the main thread
